I can't believe you stripped out an A vehicle and didn't find the following 3 items:-
1), from under the engine, a watch with a snapped leather strap.
2), A "compo" can opener.
3), A chinagraph pencil
The best 6 months I spent in the army was crewed on Ferrets in Cyprus with the Scout Car Squadron of the UN peacekeeping force. As much beer and brandy as you could drink, and a medal for your trouble.
